my reason is .. they are a sub size I have never done much of, always trying to go for multiple woofers and lots of power. I decided to try something different and be apart of the 1 sub club for once. I haven't looked back since deciding on it, it just seems so badassed to be able to say, it's just 1 10 man, then the reaction from people makes it all worth it. From a competitors stance I would have nothing to say though, don't compete and if I did, it'd be bassrace and the like. I'm not a numbers kind of guy.. but I still want to own the best a company has to offer because it makes me happier with my own system to know I got it all myself.
besides, 10s rock. That clears that up.
